its not going to be as durable as a gopro at all.
its image quality will not be close to gopro
its bit rate for video is 24Mbps compared to gopro at 60Mbps
it does not have a zoom like you mentioned above, it has a fixed lens at 16.6mm f2 and 160 degree field of view.
it only has 30 frames per second 1080 HD so youll have to go to 720 for 60 frames per second. the gopro has better high frame rates in HD (slow motion)
Zoom is also mainly an audio company that makes compact field recorders for audio and is new to the video side so im not sure how well it will work with the menus and functions.
The sound will be 1000x better than gopros
I would say go with a gopro hero 4 ($350) or hero 5 ($399), or action cam fdr-x3000 ($349) or action cam hdr-as300 ($249)
they will all be more durable and have better image quality.
the zoom q4 is $150-$130 and the $100 to $250 dollars you save don't make up for the lower quality you get
